In the knife world quite a few claims are made regarding the advantages a convex edge may have over a straight edge. In this post I examine some of these claims.
The Fallkniven A1 is a beast of a knife with a blade length of 6.3” (16 cm), a blade thickness of 0.24” (6mm) and a weight of slightly over 11 oz (305 grams). My Wicked Edge was soon to know…
I wanted to find out which method was the easiest to create a convex edge using the Wicked Edge. I created a multi-beveled edge and then stopped the blade to turn this into a convex edge.
The third method for creating convex edges on the Wicked Edge involves creating a full edge at the lowest angle (16 degrees), followed by a full edge at the highest angle (22 degrees), followed by the two intermediate bevels (20 and 18 degrees).
The second method for creating convex edges on the Wicked Edge involves creating a full edge at the highest angle (least acute), followed by setting multiple bevels at subsequently lower angles, without creating new complete edges at these angles.
In theory, this should be the fastest method, since you have to create a full edge only once. It should also be the method that results in the least amount of material being removed.
Creating a convex edge using a guided sharpening system like the Wicked Edge is not too difficult with some practice. Basically it involves sharpening the blade at different angles, creating a multi-beveled edge. These edges are then blended together by means of stropping.
